Archived Security Brief

Saturday's vulnerability disclosures include 14 critical and 100 high-priority CVEs, with three perfect CVSS 10.0 scores affecting Acronis Cyber Protect on Linux (CVE-2025-30411, CVE-2025-30412, CVE-2025-30416). Critical CVE volume dropped 42% from Friday's 24 to 14, while high-priority counts held steady at 100. Additional critical flaws affect Docker tool sandbox (CVE-2026-27002, CVSS 9.8), MLflow (CVE-2026-2635, CVSS 9.8), and Ghost CMS (CVE-2026-26980, CVSS 9.4). Twenty-one CVEs have confirmed active exploitation, spanning Microsoft Windows and Office, Apple OS, Google Chromium, GitLab, Roundcube Webmail, and Zimbra. No patches are currently available for the disclosed vulnerabilities, requiring organizations to prioritize compensating controls and monitoring.

  • Three CVSS 10.0 vulnerabilities in Acronis Cyber Protect for Linux demand immediate risk assessment (CVE-2025-30411, CVE-2025-30412, CVE-2025-30416)
  • Critical CVE count dropped to 14 from Friday's 24 (-42%), while high-priority CVEs remain unchanged at 100
  • Docker tool sandbox (CVSS 9.8), MLflow (CVSS 9.8), and Ghost CMS (CVSS 9.4) each carry critical-severity remote exploitation risks
  • Active exploitation confirmed across Microsoft Windows and Office (6 CVEs), Apple OS, Google Chromium, GitLab, and Roundcube Webmail
  • Patch availability stands at 0% β€” no vendor fixes are currently released for Saturday's disclosed CVEs
  • 21 actively exploited vulnerabilities identified, up 5% from Friday's 20

Immediate action: Prioritize Acronis Cyber Protect environments for immediate compensating controls given three CVSS 10.0 flaws with no patches available. Review exposure to actively exploited Microsoft Windows, Apple OS, and Chromium vulnerabilities, and apply network segmentation or access restrictions where patches have not yet been released.

How to read this brief

CVSS score (e.g. 9.1) β€” severity from 0–10. Red marks critical (9+), orange high (7–8.9).

Exploitability β€” how hard the flaw is to attack, read from the CVSS vector:

  • Network / Adjacent / Local / Physical β€” how close an attacker must get. Network means reachable over the internet.
  • No / Low / High privileges β€” the access they need first. No privileges means no login required.
  • No interaction / User interaction β€” whether a victim has to do something (open a file, click a link). No interaction means fully automatable.

The lower the bar on all three, the easier to exploit at scale β€” β€œNetwork Β· No privileges Β· No interaction” is the worst case: hit from anywhere, no credentials, no victim action.

Actively exploited β€” confirmed under attack in the wild (CISA’s Known Exploited Vulnerabilities catalog). Prioritize these regardless of score.

EPSS Β· Nth percentile β€” FIRST.org’s estimated chance a flaw is exploited within 30 days. We flag it only in the top 10% β€” a statistical signal it’s unusually likely to be targeted, separate from whether attacks are confirmed.
